“…However, the increase in grain yield, independently of forms of inoculation, was equivalent to 16.1% compared to control. Similar results were reported in the literature where wheat yield was between 3.1% and 11.1% greater in inoculated plants compared with non-inoculated plants [10,[56][57][58]. Fukami et al [11] reported that spray inoculation with A. brasilense either on leaves or soil can increase plant growth and can replace 25% of N fertilization on grasses.…”

The use of biological techniques such as plant growth-promoting bacteria (PGPB) can represent a sustainable alternative for cereal growth in tropical areas. Research showing the potential for management practices which optimize PGPB inoculation is of utmost importance. This research was developed to investigate the potential use of Azospirillum brasilense in wheat cropping systems, as well as to assess the potential synergistic interactions between the beneficial use of silicon (Si), principally under abiotic and biotic conditions, and A. brasilense forms of application and how they impact crop development and wheat yield. The study was set up in a Rhodic Hapludox under a no-till system. The experimental design was a completely randomized block design with four replicates arranged in a factorial scheme with four inoculation forms (control, seed, groove, and leaf) and two soil acidity corrective sources (Ca and Mg silicate as Si source and dolomitic limestone). Seed inoculation was more effective in promoting wheat growth and development, with higher yield, showing an increase of 26.7% in wheat grain yield. Calcium and magnesium silicate application associated with foliar inoculation and without A. brasilense inoculation can increase wheat grain yield.

“…For the PH, its growth occurred due to the use of nitrogen on the early stages of development, because it rises the production of phytohormones of growing promotion as the auxins and therefore, increasing the cell expansion and division (Alves et al, 2017), the same behavior was observed for the EL, due to the using of the nitrogen fertilization. As for the NSE, according to Demari et al (2016), the management of the N influences the NSE, besides that often the soil conditions that provide a propitious environment for the plants, make any response impossible due to the implemented management practices (Munareto et al, 2019).…”

Nitrogen fertilization in wheat is the item that most impacts production costs when it comes to fertilization, due to its importance and demand for this crop. Thus, organic fertilization and nitrogen fixing bacteria can be management strategies to supply the nitrogen demand. The objective of this study was to evaluate the impacts of the bacterium A. brasilense associated with organic fertilization and mineral fertilization on some plant parameters and on the final productivity of wheat grains. The experimental design was a randomized block, with 8 treatments and 8 repetitions, with the following treatments: T1: Control; T2: A. brasilense; T3: 100% N-mineral; T4: 100% N-mineral + A brasilense; T5: 50% N-mineral + 50% N-organic; T6: 50% N-mineral + 50% N-organic + A. brasilense; T7: 100% N-organic; T8: 100% N-organic + A. brasilense. The parameters of the plant and the final productivity of wheat grains showed that the use of the bacterium A. brasilense was not an efficient strategy, however, in relation to the fertilization sources in the final grain productivity, the use of urea isolated or associated with organic fertilization did not differ from each other and were superior to the other treatments.

“…According to these authors, in years favorable to cultivation, the time of fertilization with N-fertilizer was adjusted to around 45 days after emergence and in unfavorable years to 35 days. In wheat, Alves et al (2017) studied the interaction between Azospirillum and nitrogen doses applied by topdressing. The results showed that there was no interaction between nitrogen and inoculation.…”

The timing of nitrogen application in oats can improve the efficiency of use of the nutrient and the expression of productivity and quality of grains. The objective of the study was to indicate the best time of application of nitrogen in oats, considering different conditions of nitrogen dose in the sowing/topdressing in the expression of productivity and the effects on the indicators of industrial and chemical quality of grains, considering the main succession systems of cereal cultivation in Brazil. The experiment was conducted in 2018, in Augusto Pestana, RS, Brazil. The design was randomized blocks with four repetitions, in a 3 × 4 factorial scheme, with three doses of nitrogen at sowing (0, 30 and 60 kg ha-1), changing the topdressing dose by the total supply of 70 and 100 kg ha-1 in succession system soybean/oats and corn/oats, respectively, with the timings of supply in topdressing at 0, 10, 30 and 60 days after emergence. The total doses were defined looking for grain yield expectations of 4000 kg ha-1. In the management of nitrogen in oats, the absence of the nutrient at sowing and application of the total dose in topdressing around 30 days after emergence provides advantageous results, improving productivity and indicators of industrial and chemical quality of grains.
